Description

The instruction configuration method of CSI feedback signaling and base station

Technical field

The present invention relates to the communications fields, instruction configuration method and base station in particular to a kind of CSI feedback signaling.

Background technique

System is after it experienced the several versions of R8/9/10 for long term evolution (Long Term Evolution, abbreviation LTE), again R11 technology is accurately studied successively.R8 product in part starts gradually commercial at present, and R9 and R10 need further product programming.

It experienced R8 the and R9 stage, R10 increases many new characteristics, such as DMRS again on the basis of the above two (Demodulation Reference Signal, demodulated reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference signals) etc. pilot tones characteristic, 8 antennas support etc. transmission and feedback characteristics etc. Deng especially eICIC(ehanced Inter-Cell Interference Cancellin, inter-cell interference counteracting enhancing) Technology further considers the interference avoidance technique between cell on the basis for considering R8/9ICIC.For solving cell Between the technology of interference problem mainly consider that the area interference under homogenous networks avoids at R10 initial stage in stage, wherein the considerations of mainstream EICIC technology and CoMP(Coordinated Multi-point, multipoint cooperative) technology.CoMP is exactly as its name suggests multiple sections Point cooperation sends data in identical running time-frequency resource or different running time-frequency resources to one or more UE.Technology can in this way To reduce the interference between cell, the throughput of cell edge is improved, expands MPS process.But due to discussing that the later period considers Heterogeneous network introduces more scenes, and the time restriction that the complexity and R10 of CoMP technology discuss is final to determine in R10 rank Section does not introduce additional CoMP standardized content, but the demand of the part CoMP can be considered in design CSI-RS to design, institute With CoMP technology with regard to without carrying out further discussion after 60bis meeting.

LTE defines PDCCH(Physical downlink control channel, Physical Downlink Control Channel) it holds Dispatching distribution and other control information are carried, each PDCCH is by several CCE(Control Channel Element, control letter Road unit) it forms, the CCE number of each subframe is determined by the quantity and downlink bandwidth of PDCCH.

UE by search space blind Detecting obtain PDCCH, search space is divided into public search space and UE is dedicated searches Rope space, public search space refer to the region that all UE can be searched, and what this space carried is cell Proprietary Information.Specially It is the spatial dimension that single UE can be searched with search space, the dedicated search space of multiple UE is possible to be overlapped, only generally Initial searching position is different.Before blind examination, UE operating mode is notified by high-level signaling and for the cyclic redundancy check of PDCCH (Cyclic Redundancy Check, abbreviation CRC) scrambled radio network temporary identifier (Radio Network Temporary Identity, abbreviation RNTI) type.

Search spaceWith aggregation level L and candidate's PDCCH quantity M(L)Between relationship be shown in Table 1.Polymerization grade, that is, PDCCH CCE number of occupancy.When user's dedicated search space carries out blind Detecting, user equipment is first according to user identifier (UE ID) Blind examination initial position Y is calculated with subframe numbers etc.k, then detected in search space, give oneself until detecting Until PDCCH.

Table 1.PDCCH Candidate Set

The correspondence of relative position of the first control channel unit of aggregation level and PDCCH in user's dedicated search space Relationship is shown in Table 2.Relative position of the first control channel unit of PDCCH in user's dedicated search space refers to what PDCCH was occupied First CCE index nCCE and blind examination initial position YkRelative position, herein use nCCE, offset indicate, nCCE, offset=nCCE-Yk, the value range of nCCE, offset are 0 ~ 6,8,10.It as shown in table 2, is UE dedicated search space, it can First position CCE of energy and its schematic diagram of corresponding polymerization grade.

The corresponding relationship of table 2 aggregation level and first position CCE

During newest 68bis session discussing, the hypothesis about feedback and interference definition is discussed in detail, Current main viewpoint is that channel measurement and interference measurement are studied respectively, channel measurement and interference separate configurations, and And may support the aggregated feedback of different CSI-RS resource, the aggregated feedback includes polymerization PMI feedback and polymerization CQI feedback. In addition in view of the expense and descending control signaling of feedback to the size of CoMP measuring assembly be it is relevant, it is therefore necessary to elder generations The discussion and limitation of CoMP measuring assembly size are carried out, so that feedback and descending control signaling can be obtained and further be begged for By convergence.It being discussed by 68bis meeting and offline, preliminary definition CoMP measuring assembly size maximum is no more than 2 or 3, this Sample can carry out convergence appropriate with the research for further feedback and control signaling.
